This invention relates to of tire boot or adapted to improvements inpatch vwhich isV beplaced. inside the tire casing about the inner tubeto close a blow-out or .rim cut and which einbodie sleeve and a lacingconnecting the inner or' longitudinal edges of the sleeve.

connects comparatively sho inner or longitudinal edges as it ispositioned centrally s an arcuate split As it 'only rt portions of theof thesleeve and `between the ends of the sleeve, the lacing cannotfunction to hold the ends against spi thereto this boot or patch cending, and due annot be usedy effectively in connection with a tireofwhich f the casing has a Vblow-out or rim cutV of greater length thanth at of the parts of the sleeve connected by the lac rhe presentinvention h objects to improve ing.

as foro'ne o'f its this boot or patch tothe end that this disadvantagethereof maybe overcome, and to attain this end comprewith a two parttive parts are arranged at opposite 'sides of and in spaced relation tothe transverse center of the sleeve, the position being such as to holdthe parts of the lacing and length of the ends of the sleeve againstspreading and such as to obviate any liability of the diametrical andcircumferen the sleeve b eing distorted cation of the boot or patch.

A further object ofthe invention is to provide a boot or patch tialcontours v of during the appl'1-.

of the character stated with a strip of c ured rubber adapted to closethe blow-out or rim cut ina manner to prevent water, dust, sand and thelike from passing therethrough into the tire.

The invention is herein described and claimed, rand after more fullyillustrated in the accompanying drawing, wherein Figure 1 is an innerplan view of a tire boot Yor patch embodying my invention,

Figure 2 is a view in side elevation of the boot or patch, Figure 3 is atransverse sectional view taken on the plane indicated by the linesectional vieu7 taken the line 1 -4 of patch comprises an arcuate splitsleeve 1 which is adapted to he placed within a tire casing about theinner tube.

The sleeve 1, which may sired length, comprises a p be made of anydelurality of layers lacing will not when the through the bythe lacing,is longer than the sleeve, and A has cliamfered end and side edges. Theflap 2 has one'longitudinal edge thereof secured by brass rivets B tothe sleeve 1, and extends acrosslthe open inner side of the sleeve. Y

The lacing is in twoV parts, and the respecv tive parts'lf and 5 thereofare located at 0pposite-"sides ofand spaced from the transverse vcenterof tliersleeve 1. Each part off the lacing comprises a series of wireloops 6 secured ytoy one ofthe. vinner or longitudinal edges ofthesleeve,=and la series of similar elements 7 secured to the other; innerorlongitudinal edge of the sleeve. G and Tof each part of the lacing arearranged to overlap, and are connected together by a vpin 8. y

As the parts 4 and at opposite sides of and transverse center of thesleeve 1, and as the outer ends of said parts are located comparativelyclose to the ends of the sleeve, the lacing will prevent the ends of thesleeve from spreading, with the result that the boot or patch may beused effectively Vin connection with a tire of which the casing has a'blow-out or rim out greater in length than the connected .portions ofthe inner or longitudinal edges of the sleeve, but of less lengththereof areV arranged The wire loops spaced from the i than the sleeve.Due to the manner in which Y the lacing parts 4 and 5 are arranged. withrespect to thetransverse center of the sleeve 1, and as their outer endsare spaced fromr the sleeve, lthe loops 6 and 7 thereof are connecteddistort the diametrical and circumferential contours of the sleeve, Theopen space between th-e parts of the lacing permits the boot or patch toexpand suiliciently to adapt it to snugly fitthe injured part of thetire casing. Y

A strip 9 of cured rubber is secured to the the corresponding ends ofouter surface of the sleeve 1, and is adapted to seal or close theblow-out or rim cut in the tire casing so as to prevent water, dust,sand and the like from entering the wtire casing blow-out or rim cut Thestrip and is secured arranged 9 is of triangular formation tothe sleeve1 with its base edge in close parallel relation to one of the inner I orlongitudinal edges of the sleeve. The circuiiiiterential dimension ofthe strip 9 is less than the corresponding dimension of the sleeve l.The strip 9 is protected by a strip l0 voit holland cloth which issimilar in contour thereto and is to be removed imme# diately prior tothe application oiu the boot or patch. The strip 9 is secured to thetire casing by cement which is applied to the `latter about the injuredpart thereof. The boot or patch may be so arranged Within the tire as toproperly position the rubber strip 9 `for sealing a blow-out or rim cutin either sidey or in the tread oi' the tire casing, as will beapparent. As the strip 9 is of triangular contour, it does not extendover tlie entire outer surface of the boot or patch and will nottherefor-e materially reduce the flexibility oi the boot or patch. Thestrip 9 affords full protection for the reason that a tire casing isseldom ii:l ever rim cut on both sides and for the reason that the bootor patch' may be arranged Within the tire casing iii a manner toposition the base of the strip adjacent the rim cut.

It should be understood that the rdrawing is merely illustrative anddoes not pretend to give exact proportions. Furthermore, the drawing isillustrative of a preferred construction, it being my expectation thatvarious changes and modications may be made Without departing from thespirit and scope oli' my invention.

l/Vhat is claimed is :M

l. A boot or patch comprising a split yinner or longitudinal edges ofsleeve, and a tivo part lacingconnecting the inner or longitudinal edgesof the sleeve,

the respective parts of the lacing being ar- Vranged at opposite sidesof the transverse center lot' the sleeve. I

2. A boot or patch comprising a split sleeve, and a two part lacingconnecting the the sleeve, the respective parts of the lacing beingarranged at opposite sides and spaced from the transverse center of thesl-eeve. l

3. A boot or patch comprising a split sleeve, and al multiple partlacing connecting the inner or longitudinal edges of the sleeve, therespective pai-ts of the lacing being arranged between the transversecenter and Athe ends of the sleeve.

at. A boot lor patch comprising aI split sleeve, a lacing connecting theinner or longitudinal edges of the sleeve, and a strip of cured rubberof triangular contour secured to the outerk surface of the sleeve Withits base edge in parallel arrangement with one of the longitudinal edgesot` the sleeve.

5. A boot or patch, comprising a split sleeve, and means connecting the,inner or longitudinal edges of the sleeve in a manner to leave thecentral portions of said edges tree so as to permit the' central portionof the sleeve to expand sufficiently for snug engagement with an injuredpart of a tire casing.

In testimony whereof I atlix my signature.
